Yes. The A39 Geometric Case is designed specifically for AirPods Pro 3. It includes precise cutouts for the speaker and charging port, keeps the front LED indicator visible, and supports easy pairing access without removing the case.
Yes. The A39 is designed for uninterrupted wireless charging, so you can charge your AirPods Pro 3 without removing the case. It can work with compatible MagSafe-style wireless charging setups when the AirPods charging case and charger are properly aligned, but the A39 case itself is not designed to add extra magnetic hold.
The A39 uses a thickened TPU shell for everyday protection, a zinc alloy lock clip to help keep the case securely closed, and PC material as part of the overall structure. This combination gives the case a more protective feel while keeping the geometric design clean and structured.
The geometric shape is part of the case structure, not just a printed surface pattern. The fine matte finish is designed for daily use, but visible wear may still occur over time depending on friction, impact, and how the case is carried. To keep it looking better, avoid sharp objects, abrasive surfaces, and harsh chemical cleaners.
The A39 is built for stronger everyday protection, so it has a more structured feel than a basic thin silicone cover. It weighs about 45 g and measures approximately 73 × 64 × 32 mm, balancing protection, portability, and a comfortable in-hand experience.

Designed for users who want stronger everyday protection without losing portability or style, the A39 Geometric Case for AirPods Pro 3 combines a reinforced TPU shell, secure zinc alloy lock, detachable anti-loss lanyard, and a distinctive geometric design in a case built for modern daily carry.
The A39 is built for users who want their AirPods case to feel more distinctive than a standard smooth cover. Its structured geometric silhouette gives AirPods Pro 3 a more technical and design-forward look, making it a better fit for users who care about both protection and visual detail.
More than a decorative shell, the A39 uses a thickened TPU body to help protect your AirPods Pro 3 from drops, scratches, bumps, and daily wear. With full-cover construction and a more durable outer structure, it is designed to give users more confidence during commuting, travel, and on-the-go use.
A protective case works better when it stays closed securely. The A39 features a precision-cut zinc alloy lock clip that helps keep the case shut more reliably, reducing the risk of accidental opening and adding an extra layer of security when your AirPods are in a bag, pocket, or clipped to your gear.
The A39 balances protection with a more refined tactile feel. Its fine matte finish, ergonomic form, and metal detailing create a case that feels more comfortable to hold while also giving it a more premium and durable everyday character.
For users who want easier access on the go, the detachable lanyard adds more flexibility to how the case is carried. Whether attached to a bag, wrist, or everyday setup, it helps reduce the chance of misplacing your AirPods while making the case more convenient for travel and active routines.
The A39 is made to keep key functions easy to use without removing the case. It includes precise cutouts for the charging port and speaker area, keeps the front LED indicator visible, supports easy pairing access, and remains compatible with uninterrupted charging for a more seamless user experience.
